Development of Wireless embedded system using ZigBEE protocol to avoid white Gaussian noise and 50 Hz Power line noise in ECG and Pressure Blood signals

Abstract

Electrocardiogram (ECG) and Pressure blood is a main source for doctors to diagnose the health condition and pathology of heart. The magnitudes of ECG signals are usually approximate 1mV. The Electrocardiogram signals are affected by environment noises. The mostly sources of these errors are the power line of 50HZ. In this paper we present an advance develop of Wireless pads using embedded system and ZigBEE protocol to avoid white Gaussian noise and 50 Hz Power line noise from ECG and Pressure Blood measurements signals. The user-doctor can acquire from the internet in real time the electrocardiograph and the pressure blood of patient. On system can be connected Bio-instrumentations via RS 232 protocol. Finally all information can be imported in BioBench Software. © 2008 IEEE.
